i serched for 2 hours and got all the info i could !

then i got some rubber vacum caps and some vacume line and a got a vacum T

yanked everything off then capped it except i kept a vacum line hooked up to distributer stuff (cant remeber the technical word right now haha)

no more cruise control and no more AC step up haha

and the engine doesnt start as easy as it used to... haha


but damn its looks alot better

hey not to sound like a newb.... but how the hell do i post multiple pics.. i documented the whole process and wanna post it step by step so people have a new thread to look at instead of those pics for the older emissions style 1st gens...

Okay, you'll have to forgive me for the newbie question but what does the rat's nest do for the car?

It sounds like vacuum control for the cruise control. But what is an A/C step up? What other purpose does it serve/what systems are impacted by its removal.

Thanks!

(P.S.) very close to a deal on an 85 GSL

Why not pull out all that AC crap! How does it run? I'm thinking of pulling my nest out. I don't have cats, so it's pretty much usless anyway. Did you run a vacume line from the carb vent and the filler neck to the air filter housing or charcoal canister?

rotary love,

the rast nest is all that emissions crap on top of the engine.... vacum hoses blah blah colored thingys on the top of the engine ....

as for what it does.... hmm not a whole lot ,if any, performance wise
but it sure looks a hell of alot nicer.... if your emissions sytem was failing and ya had some vacum leaks or sumthing ( like i think i did) ya prolly feel a nicer ( not nessesarily(sp) fatser) top end

oh and the ac step up is the thing that ups your rpm when the ac is turned on (i think)

the pic to DL is of what it looks like at the start... then i will post a pic of what mine looks like now

rotary love.... this is what it looks like now.........
sorry bout the quality but my digital camera took a sh*t
so i had to use my old one

but see how you can see the top of the engine now and all that grime i cleanned off

rollin82

haha for some reason i think someday my ac will randomlly start working... but as for the vacum line from the neck.. uh thats on my to do list.. looking for a tiny breather to attach.... but ya i should do sumthing.........


and as for it running good... its no faster 0-60.. and i havent had a chance to test my 1/4 yet.... but it feels alot nicer up top...

but it doesnt like to start as easy ( any body know why this might be?)

I'm guessing that it has something to do with your vaccuum advance and timing. You might try "locking your timing". I haven't tried it personally, but I plan on doing it to my 79. (eventually)
Block the end of the vac. line on the engine and leave the distributor vac. advance lines open. The set your timing with the engine at 4k RPM.

While you're at it, why not move to DLIDFIS?

(BTW, did I mention this is just a guess?)

haha that yaw guy makes my brain hurt

yeah, this stuff gets complicated sometimes. I've been doing some reading lately on the subject. When most everyone talks about distributors or ignition stuff they already assume you know the terminology and abbreviations, but somehow don't know how it works. So, they rant on in abbreviations and terminology and i got no clue....



Oh, well, I'll get it one of these days...
